MACHINE-=GUN.

SPECIFICATION forming part of Letters Patent No. 426,356, dated April 22, 1890.

Application filed January 2, 1890. Serial No. 335,650- (No model.) Patented in England June 18,1888,No. 9,455; in France April 20, 1889, No, 197,625; in Belgium April 23, 1889, No. 85,942, and in Austria-Hungary September '7, 1889, N0. 39 and To all whom it may concern.-

Be it known that 1, JAMES GEORGE ACCLES, engineer, a citizen of the United States of Americairesiding at 41 Craven Street, Strand, in the county of Middlesex, England, have invented certain new and useful Improvements in Machine-Guns, (for which I have re ceived Letters Patent in Great Britain, No. 9,455, dated June 28, 1888; in France, No. 197 ,625, dated April 20, 1889; in Belgium, No. 85,942, dated April 23, 1889, and in Austria- Hungary, No. 39 and No. 1,926, dated September 7, 1889,) of which the following is a specification.

My invention relates to machine-guns of the Gatling type in which there are a number of barrels ranged around a cylinder and revolve about its axis. I carry the axis of the handle for giving motion to the barrels through one of the trunnions upon which the gun is mounted.

Figure 1 shows a side elevation of a Gatling gun embodying my invention. Fig. 2 is a front end elevation. Fig. 3 is a rear end elevation. Fig. 4 is a transverse section on the line 00 00, Fig. 1. Fig. 5 is a side elevation of the clutch and rod for working it. Fig. 6 is an end elevation of the same. Fig.- 7 is a modification of Fig. 4. Figs. 4 to 7 are to a larger scale than Figs. 1 to 3.

The drawings do not show the details of the feeding, firing, and extracting mcchanism,as these are well known and form no part of my present invention.

a. is the casing of the gun, and Z) Z) are the barrels.

c is the handle for giving motion to the barrels. The axis (Z, to which the handle 0 is fixed, passes through one of the trunnions 2, upon which the gun is mounted and drives at its inner end the worm f, which gears with the worm-wheel g, fixed to the barrels.

In Fig. 7, the worm f and worm-wheel g are replaced by the beveled pinion f and wheel 9'. The shaft cZ and worm f are connected by clutch-surfaces h and j, fixed to them respectively. The surface h can be moved endwise upon the shaft (Z to throw the clutch into and out of gear by means of the fork 70, but is prevented by a feather from turning upon the shaft, as is clearly shown in Figs. 4 and 5. The fork is is fixed to a rod Z, passing to the rear of the gun, so as to be within reach of the gunner there. Its rear end carries thumb and finger pieces or handles Z Z, by which the clutch can be thrown into and out ofgear. The rod is prevented from turning back again by a spring-click contained in the box in.

In Fig. 7 the rod Z and parts connected to it are omitted, the handle being held in gear by the pin 01, which enters a groove in the shaft CZ.

\Vhat I claim is 1. The combination, substantially as hereinbefore set forth, of a revolving gun, its trunnions, an axis passing centrally through one of the trunnions, and gearing operative] y connecting the axis with the gun.

2. The combination, substantially as hereinbefore set forth, of a revolving gun, a toothed wheel fixed to the gun, the gun-trunnions, an axis passing centrally through one of the trunnions, and means for connecting the toothed wheel on the gun with the axis.

3. The combination, substantially as hereinbefore set forth, of a revolving gun, a wormwheel fixed to the gun, an axis passing centrally through one of the trunnions, and a worm connected to the axis and gearing with the Wheel on the gun.

4. The combination, substantially as hereinbefore set forth, of a revolving gun, its trunnions, a worm-wheel fixed to the gun,an axis passing centrally through one of the trunnions, a worm gearing with the worm-Wheel on the gun, a clutch for connecting the Worm to the axis, and a clutch-operating rod extending to the rear of the gun.
